add 4 each time

the nth term is a_n or f(n)

the next term after that is a_{n+1} or f(n+1)

so each term is 4 more than previous

basically

a_{n+1}=4+a_n or

f(n+1)=4+f(n)

same thing

Answer:

C

Step-by-step explanation:

Using the sine ratio in the right triangle.

sinC = \frac{opposite}{hypotenuse} = \frac{AB}{BC} = \frac{16}{28} , thus

∠ C = sin^{-1} (\frac{16}{28} ) ≈ 34.85° ( to 2 dec. places )

Which equation matches the graph below?
Oksana_A [137]

Answer:Given that the graph shows tha the functión at x = 0 is below the y-axis, the constant term of the function has to be negative. This leaves us two possibilities:

y = 8x^2 + 2x - 5 and y = 2x^2 + 8x - 5

To try to discard one of them, let us use the vertex, which is at x = -2.

With y = 8x^2 + 2x - 5, you get y = 8(-2)^2 + 2(-2) - 5 = 32 - 4 - 5 = 23 , which is not the y-coordinate of the vertex of the curve of the graph.

Test the other equation, y = 2x^2 + 8x - 5 = 2(-2)^2 + 8(-2) - 5 = 8 - 16 - 5 = -13, which is exactly the y-coordinate of the function graphed.

What value of x makes the following equation true?<br> 15+3x=3(2−2x)
Alinara [238K]

Answer:

\boxed {x = -1}

Step-by-step explanation:

Solve for the value of x:

15 + 3x = 3(2 - 2x)

-Use <u>Distributive Property</u>:

15 + 3x = 3(2 - 2x)

15 + 3x = 6 - 6x

-Take 6x and add it to 3x:

15 + 3x + 6x = 6 + 6x - 6x

15 + 9x = 6

-Subtract both sides by 15:

15 - 15 + 9x = 6 - 15

9x = -9

-Divide both sides by 9:

\frac{9x}{9} = \frac{-9}{9}

\boxed {x = -1}

Therefore, the value of x is -1.
